A/N: Izuku and Mei get it on. Izuku turns out to be very… enthusiastic in bed.

-x-X-x-

Right. Yes. Exploring the manor and securing All For One’s files came first.

“We should-mmph!”

Only before Izuku can say as much, Mei silences him with yet another kiss, the third in as many hours. This time, her arms wrap around his neck and she all but clings to him as she smashes her lips into his own. Izuku doesn’t try to stop her though, his hands going back to her hips as they all but pick off where they were back at the previous location.

After a moment they come up for air and Mei gives him a look that promises quite a lot of pain if he doesn’t go along with her desires.

“I had a feeling you were about to say something foolish, Izuku. Right now, the only thing on your mind… should be me.”

Well when she put it like that, how could he honestly disagree? Especially seeing how Mei pulls back a moment later and shucks off her top, stepping backwards towards the bed while her breasts, clad in nothing but a bra, bounce and jiggle from the sudden motion.

Izuku… swallows hard and follows her as she all but leads him to the bed. Clothes come off, undergarments too, and before he knows it he’s holding a naked Mei in his arms, laying her back on the bed and leaning over her as his cock is stroked to fully erect by her eager hands.

“Mei… I didn’t know…”

His trustworthy and stalwart engineer huffs up at him.

“Of course you didn’t. I didn’t want to distract you… and I didn’t want you to send me away either. But seeing as you’re not exactly telling me ‘no’ now, I have to assume you’ve realized that you feel the same way about me as I’ve felt about you… for over a decade at this point.”

A… a decade? Izuku flushes a little bit but ultimately nods. Mei is right, after all. He is just now realizing that he feels a certain way about her.

“Then… I’m all yours.”

With that said, Mei guides his cock to her entrance, her slit already wet for him as he gasps from the sensation of her folds spreading open and sucking the head of his member inside of her.

“Please Izuku… take me.”

Like she’d already said, he’s not about to say ‘no’. There is a bit of self-consciousness involved because… Izuku has never been with a woman before despite being in his mid-twenties. He simply hadn’t had the time or the interest. His focus had been singularly on hunting All For One down and avenging All Might. Nothing else had mattered.

But that was done now… and Mei, beautiful and loyal Mei, was right in front of him. Under him, really… and with the entrance of her cunt already clenching down around his cockhead. With a sound that’s half-grunt, half-sigh leaving his lips, Izuku thrusts forward, spreading her wider still for his member and filling her up with every last inch.

Mei cries out, arching her back and lifting her chest into the air as her breasts jiggle while she moans.

“Mm, Izuku… you’re big~”

He tries not to get too big of a head over that, though it does bring something of a grin to his face. Of course, there’s a question of how he’s supposed to answer. Is he supposed to compliment her tightness or the size of her breasts or something?

In the end, Izuku decides to err on the side of caution and doesn’t answer Mei with words at all. Instead, he answers with actions. Leaning forward, he captures one of her breasts in his mouth and grasps the other with a hand. His other hand goes down to grip her hip, holding her in place as he begins to fuck her while sucking and groping her tits.

Gasping, Mei shudders beneath him some more, her voice growing higher pitched as she squeaks.

“I-Izuku!”

He wants to show her a good time. No, rather, he NEEDS to show her a good time. Izuku doesn’t want to be a disappointment. He doesn’t want to leave her wanting for anything. And so, for the first time… Izuku finds himself drawing on some of his new power. The library of Quirks that now exists within him answers the call easily thank fucking god, and Izuku soon finds a certain confidence he’d been lacking initially.

Calling them ‘sex quirks’ would be an insult to the victims that All For One stole them from, while also just being plain wrong. Rather, they’re Quirks with multiple uses… and one of those uses just so happens to be ‘having good sex’.

Stuff like stamina boosting to make sure he can go as long as Mei wants him to or extrasensory so he doesn’t just have to rely on her moans and mewls to figure out if she’s enjoying what he’s doing or not. In the end, it’s about ten Quirks he pulls on to show Mei the absolute best time he can… and the effects are immediate.

“W-Whoa! Izuku… oh god, Izuku!”

Mei squeals as she cums all over his cock, explosively orgasming along his pistoning shaft. A slightly vicious grin spreads across Izuku’s face, even as his teeth remain latched onto one of her nipples. Smooth as can be, he switches from one nipple to the other, giving both of her breasts the attention of her mouth.

At the same time, the hand that had been on her hip moves to her abdomen instead, pressing down on her belly. If he concentrates, he can feel his cock pistoning in and out of her through her flesh, his palm able to push and apply a bit more pressure for her.

“Hnnngh, Izuku… don’t stop! Please, more!”

Her arms and legs wrap around him in turn, almost involuntarily as they cling to him seeking more of the pleasure he has to offer. Feeling on top of the world, Izuku keeps going. He keeps fucking her with everything he has. Every orgasm feels like a triumph. Every climax feels like a win. Making Mei cum her brains out for him… well… it feels a little like taking a victory lap, doesn’t it?

PLAP! PLAP! PLAP!

Time loses all meaning as Mei shudders, quivers, and quakes under him. His beloved engineer, the woman who has stood with him through thick and thin, is brought to the heights of ecstasy time and time again. This woman who has helped him for over a decade… and who has apparently carried this torch for him for almost all of that time… she deserves everything Izuku can give her.

Now that he’s apparently inherited All For One’s wealth, Izuku will hopefully be able to give Mei what she needs financially. Maybe she’ll be able to start her own company for support gear even, since that’s something Izuku is well aware she’d planned to do before she truly fell in with him.

But such things can be discussed tomorrow. Right now, what Izuku can give Mei is a whole boatload of pleasure so that’s exactly what he does, pounding her pussy into the shape of his cock until she’s begging him to finally cum.

Wait… Izuku blinks and pauses, realizing he got caught up in things a bit too much. Staring down at Mei, he realizes she’s not begging for more anymore. Instead…

“P-Please Izuku… I don’t… I don’t think I can take much more. Please cum for me. F-Fuck, I feel like I’m going insane.”

Oh. Whoops? He might have… gone a little overboard there. His cock is throbbing and pulsing and all too ready to cum, but he’d been consciously holding back his release, delighting in making Mei climax some more instead. Only… she’s probably orgasmed for him dozens of times at this point, hasn’t she?

Hiding his chagrin, Izuku leans down and brushes a lock of hair out of Mei’s sweaty face, giving her a fond smile.

“I’m going to cum, Mei. You’re going to make me cum.”

Mei moans, nodding enthusiastically and excitedly. He thrusts into her a few more times before finally tipping over the edge and letting her weakly clenching insides finally milk him of his seed. Izuku groans as he empties himself inside of her, shuddering a bit while he fills her up. Mei softly moans, before slumping back on the bed, looking like she might pass out at any moment.

He’s exhausted her, Izuku belatedly realizes. Truth be told, he doesn’t know how long its been, but it doesn’t really matter in the end. As he pulls out of Mei’s cunt, she just shudders.

“I think… I think Ima pass out now, Izuku. That was… really fun.”

Well, that helps his guilt a little bit at least. Although Izuku himself now has a problem… thanks to the Quirks he used, he’s not even remotely tired. He feels like he probably SHOULD lay down and cuddle with Mei, but he’s a bit too wired for that. At some point Izuku is going to have to learn to control this stuff… but for now, he decides to take it as a sign that he isn’t done yet tonight.

“I’m going to check the place out and try to find All For One’s files, Mei. You get some sleep, alright?”

Mei looks at him through tired, lidded eyes and just nods wordlessly. Izuku gets dressed and gives her one last slightly apologetic smile before heading out of the Master Bedroom to search the rest of the manor.

-x-X-x-

As Mei watches Izuku go, she lets out a sigh while experiencing another full body shudder, the aftershocks of sex with the man once again running through her. Fuck… he was dangerous. Exceedingly dangerous. Sex with Izuku was… like nothing Mei had ever experienced before. To be fair, it wasn’t like she had much sexual experience to begin with even if she wasn’t a virgin, but this… this was like a volcano next to a candle.

Izuku Midoriya was a beast in bed and the funny thing is, Mei would have said he was a virgin before what she just experienced. But there was no way that was the performance of someone having their first time… was it?

Ultimately, did it matter? Not really. No, what really mattered was the plain and simple truth that Mei just had etched into her tired, quivering, trembling body. She wasn’t enough. Fuck, she hadn’t even managed to tire Izuku out enough for him to cuddle with her afterwards!

… If she was going to tangle with Izuku fucking Midoriya, Mei was either going to have to develop something to help her keep up with him… or she was going to have to recruit some other women capable of sharing the load. She never thought she’d be contemplating sharing Izuku with another woman (or several), but then to be fair she never quite thought she’d manage to bag him either. For a long time Mei had assumed one or both of them would die before she ever got the chance to truly express her feelings.

It’s a whole new world now though… and Izuku is the kind of man who has just proven that he’s going to be a LOT to handle.

And yet… Mei really wouldn’t have it any other way. With an extremely satisfied smile on her face, Mei Hatsume finally allows herself to drift off to sleep.

-x-X-x-

Sitting in a study staring at a computer screen, Izuku frowns. As he’d feared, he’s run into a bit of a wall.

After leaving the Master Bedroom, Izuku was a paradoxical mixture of annoyed and happy that Kurogiri wasn’t waiting right outside the door or anything. On the one hand, it would have been creepy to have him just… standing there. On the other hand, it would have been convenient.

Instead, Izuku had searched out the heteromorph for a bit, eventually using another Quirk to locate the swirling mass of purple mist in a suit. From there, he had Kurogiri take him to All For One’s files, which is how he wound up where he is now in the manor’s study.

As expected, there’s plenty of paper files… in fact, so many paper files that they fill up the massive mahogany cabinets that line the study’s walls from top to bottom. Encased behind glass doors, the paper files are both inviting and daunting in appearance. On the one hand, Izuku wants to know everything they contain. On the other hand, even Quirk-Assisted, reading them is going to take days if not weeks.

So of course rather than immediately cracking open the first cabinet, he’d gravitated to the study’s piece of technology… a computer monitor sitting on a large mahogany desk on one side of the room. The chair behind the desk is one of those high-back, extremely comfortable chairs that felt like it was probably worth more than most people’s paychecks. And the desk itself… well, it was certainly stunning.

But all of that is meaningless in the face of the computer monitor he’s staring at right now. The monitor which, after he’d turned on the PC attached to it, had subsequently asked him for a password. A quick glance around the desk had not unearthed anything written down on a post it note, unfortunately. All For One wasn’t THAT stupid.

Or maybe he was but seeing as this manor was made for his new life and had never been lived in before, that sort of thing hadn’t exactly had a chance to happen yet. No, there was no conveniently placed password on the desk or in its drawers.

The computer monitor and its input box seem to almost be taunting Izuku as he glares at them. How the fuck is he supposed to know what All For One’s password is? Sure, he knows how All For One was expecting to know it, but-

Wait… maybe that’s it. All For One knows the password. Obviously. And technically… All For One’s memories exist inside of Izuku. So maybe that was how he could find out the password? Just a quick dive into his own mind, pluck the password out of All For One’s memories, and come right back without risking too much.

… Izuku glances down at his hand to see it shaking. He thins out his lips before grimacing. Since when was he so cowardly that this sort of plan scared him? No… he knew why it scared him. Because he’d almost lost everything to All For One. And not just All For One, he’d almost drowned in that ocean of power lurking inside of him.

He wasn’t sure he wanted to play around with it this soon. But at the same time… Izuku knows there’s bound to be a treasure trove of information on the computer in front of him. So maybe… it’s worth it?
